score: Add Watchdog_Iterator
Rewrite the _Watchdog_Insert(), _Watchdog_Remove() and
_Watchdog_Tickle() functions to use iterator items to synchronize
concurrent operations. This makes it possible to get rid of the global
variables _Watchdog_Sync_level and _Watchdog_Sync_count which are a
blocking point for scalable SMP solutions.
Update #2307.
